Triethylenetetramine TETA (CAS 112-24-3) is a hygroscopic amine that appears as a colorless to light yellow or amber viscous liquid with an ammoniacal odor, forms a crystalline hydrate with water, and serves as a curing agent for epoxy resins, in adhesives and coatings, and in oil additives for lubrication. Less dense than water. Combustible, though may be difficult to ignite. Corrosive to metals and tissue.
